Nook Glowlight 3

For me, the simple answer is to use Calibre.  The metadata directory can get confused (I have 450+ books) but if so, I just wipe the book, reinit it and download everything anew.

Nook Glowlight 3 - "This book has been returned" and "Error opening book. Loan token update failed."

I love my new Nook Glowlight 3. But last week I was unable to open ePUB books from the public library ("This book has been returned" error). Had sessions with Nook and Overdrive support. Did a factory reset of Nook, deregistered and reregistered ADE on my Mac (Sierra), upgraded ADE from 4.5.6 to 4.5.7, and tried to install ADE 3.0, to no avail. Along the way, the "returned" error turned into "Error opening book. Loan token update failed." Needless to say, many wasted hours.

The issue is resolved by switching from Adobe Digital Editions 4.5.7 to ADE 3.0, but 4.5.7 must be uninstalled in order to install 3.0. Here's how I resolved the issue. It looks like a lot (14 steps!) but actually only took five minutes.

1. De-authorize ADE 4.5.7 on Mac
2. Uninstall ADE 4.5.7 by moving ADE files from Applications to TRASH
3. Empty TRASH
4. Download Adobe Digital Editions 3.0 from Adobe website and install
5. Any remaining Overdrive EPUB library books will still be in ADE, “remove” (not return) them from the ADE library
6. Close ADE
7. Connect Nook to computer
8. In Finder under Devices, Nook, delete Digital Editions folder
9. Eject Nook
10. Re-download desired ePUBs from public library (Overdrive)
11. Transfer downloaded books to ADE as usual; for transfer to be completed, ADE will request user ID and password to re-authorize computer
12. Connect Nook to computer
13. In ADE, transfer ePUBs to “Nook”
14. When completed, eject Nook

Hope this is helpful. Happy reading!

Up until I got a different newer glolight nook last week was able to use Adobe 4,57 to put library books on my nook. Plug nook into PC , open nook file, open first sub file, internal storage and nook shows up again, just copy and paste your ebooks into that file. It should be fine. My problem is I can't even get the adobe software to open. Have been trying everything I can think of.

Frankly I think Kindle and Adobe are in cahoots with each other and want to put Nook out of business. You notice their  new software Libby can go from library to Kindle directly. It seems like rotten eggs to me.

Don't know if this will help you at all, but good luck
